This is the customized Bubble Walker with a customized Krang figure inside.
For the Bubble Walker, it was necessary to rebuilt the rear part of the walker, both sides of the view-glass, the front panel for Krang´s tentacles and the bottom of the walker.
After this, I repainted the new walker. I used wood, cardboard and small parts of a pencil and ballpoint pen.
Because I didn´t want to cut in the original Krang figure, I decided to create a custom one. I used crumpled paper fixed with glue for the brain and tentacles and cardboard for the brain-humps. After this I painted Krang´s eyes and teeth.
